+1.2.0
+-----
+
+New
+~~~
+- Docs: Include script on how to release.
+- Scripts: Add script to help new releases.
+- Add gitchangelog template.
+- Add gitchangelog configuration file.
+- Docs: Add bwauths list image.
+- Relaylist: Keep relays not in last consensus.
+  Keep the relays that are not in the the last consensus, but are not
+  "old" yet.
+- Util: Add function to know if timestamp is old.
+  Part of #30727.
+
+Changes
+~~~~~~~
+- Stem: Set default torrc options.
+  when connecting to an external tor and they are not already set.
+- Generate, cleanup: Use 28 days of measurements.
+  When generating the Bandwidth File as Torflow, use 28 days of past raw
+  measurements instead of 5, by default.
+  Also keep the raw measurements for that long before compressing or
+  deleting them.
+  And stop checking whether the compression and delete
+  periods are valid, without checking defaults first and based on
+  arbitrary values.
+- Stem: Add function to connect or start tor.
+  Move initialization via existing socket to this new function and start
+  tor only when it fails.
+- Stem, scanner: Change args initializing controller.
+  to check whether the external control port configuration is set.
+  There is no need to assert all argument options nor to return the error.
+- Config: Add option to connect to external tor.
+  via control port.
+- Circuitbuilder: Remove not used attributes.
+  and make argument optional.
+- Circuitbuilder: Simplify building circuit.
+  Since sbws is only building 2 hop paths, there is no need to add random
+  relays to the path, or convert back and forth between fingerprint and
+  ``Relay`` objects.
+  This will eliminate the circuit errors:
+  - Tor seems to no longer think XXX is a relay
+  - Can not build a circuit, no path.
+  - Can not build a circuit with the current relays.
+  If a relay is not longer running when attempting to build the circuit,
+  it will probably fail with one of the other circuit errors: TIMEOUT,
+  DESTROYED or CHANNEL_CLOSED.
+- Scanner: Stop storing recent_measurement_attempt.
+  because it stores a timestamp for each attempt, which makes state.dat
+  grow thousand of lines (json).
+  Closes #40023, #40020
+- V3bwfile: Exclude relays without observed bw.
+  and without consensus bw from scaling.
+  Part of #33871, closes #33831.
+- V3bwfile: Percentage difference with consensus.
+- V3bwfile: Calculate hlimit from scaled sum bw.
+  instead of bw before scaling.
+  Tests have finally correct value.
+  For 1 result, only when the cap is 1, the value will be equal to the
+  rounded bw because the cap does not limit it.
+- V3bwfile: Obtain consensus values from last consensus.
+- V3bwfile: Round scaled bandwidth after capping.
+  Make tests pass because the high limit change the expected values,
+  but the final value still needs to be fixed.
+- V3bwfile: Change logic obtaining min bandwidth.
+  Take either the consenus bandwidth or the descriptor bandwidth if
+  one of them is missing, do not scale when both are missing and
+  ignore descriptor average and burst when they are missing.
+- V3bwfile: Scale relays missing descriptor bws.
+  Scale relays without average or observed bandwidth.
+  Later it will be check what to do if their values are None or 0
+- V3bwfile: Stop making mean minimum 1.
+- V3bwfile: Calculate filtered bandwidth.
+  for each relay, calculate the filtered mean for all relays and
+  calculate the filtered ratio for each relay.
+- Scaling: Add filtered bandwidth function.
+  to calculate the filtered bandwidth for each relay.
+- Bwfile: Test KeyValues in a bandwidth file.
+  Added:
+  - library to check whether the KeyValues make sense
+  - test an example bandwidth file
+  - a command to check an arbitrary bandwidth file
+  Finally, doing something with all these KeyValues!
+  (Quarantine day 7th)
+- V3bwfile: Count recent relay's monitoring numbers.
+  using timestamps class.
+  Also add one more result to the tests data and change the
+  test accordingly.
+- Tests: Remove `_count` from attr.
+- Resultdump: Add missing attrs to errors.
+- Resultdump: Remove `_count` from attributes.
+  Tests wont' pass with this commit, they'll be fixed in the next commits
+- Relayprioritizer: Count priorities with timestamps.
+  in RelayPrioritizer:
+
+  - Rename recent_priority_list_count to recent_priority_list when
+    there is no counting
+  - Rename recent_priority_relay_count to recent_priority_relay
+    when there is no counting
+  - Use the timestamps class to manage/count priority lists/relays
+- Relaylist: Count measurements with timestamps.
+  in RelayList:
+
+  - Rename recent_measurement_attempt_count to recent_measurement_attempt when
+    there is no counting
+  - Use the timestamps class to manage/count measurement attempts
+- Relaylist, v3bwfile: Count consensus with timestamps.
+  in RelayList:
+
+  - Rename consensus_timestamps to recent_consensus
+  - Rename recent_consensus_count to recent_consensus when there is
+    no counting
+  - Use the timestamps class to manage/count consensuses
+  - Remove method not needed anymore
+- V3bwfile: Convert datetime to str.
+- Resultdump: Use custom json encoder/decoder.
+- State: Encode/decode datetimes.
+- Json: Create custom JSON encoder/decoder.
+  to be able to serialize/deserialize datetime in the state file.
+- Timestamps: Add module to manage datetime sequences.
+- State: Add method to count list values.
+
+Fix
+~~~
+- Clarify release script dependencies.
+- Use rst changelog template.
+  and put in the same entry commit subject and body removing new lines.
+- Correct network stream and filtered bw.
+  because Torflow is not using them by relay type.
+- V3bwfile: network means without relay type.
+  This reverts commit fc3d3b992ada601a6255f8a6889179abd4b7e55e and partially
+  reverts a82c26184097bea3ca405ae19773de7c4354a541.
+  It was a mistake to think torflow was using the means by relay type,
+  it actually sets the same networks means for all relay types.
+  Closes #40080.
+- Semi-automatic correction of typos.
+  Closes #33599.
+- Tests: Add codespell configuration.
+- Tests: Additional security tests.
+- CI: Use all tox environments for python 3.8.
+- 2nd round of automatic format.
+  black insists to keep one long line and flake complain, therefore make
+  flake to ignore it.
+- Flake8 errors.
+- Reorder imports with isort.
+- Reformat all with black.
+- Move to declarative setup.cfg.
+  Also:
+  - Update versioneer
+  - And include other source distribution files in MANIFEST.in
+  - Add project URLs
+  - Add formatter and linter dependencies and configurations.
+  - tox: Remove travis, fix python environments
+  - tox: Remove extra coverage options and add them in .coveragerc.
+- Indent by default to 2 except python files.
+  also uncomment final newline. Can be commented again in case it fails
+- V3bwfile: network means by relay type.
+  Calculate network stream and filtered bandwidth averages per relay
+  type, to obtain bandwidth weights the same way as Torflow.
+  Closes #40059.
+- Scaling: Return mean if no bw >= mean.
+- Scaling: Stop returning 1 as the means minima.
+  since they are used as the numerator when calculating the ratio and the
+  rounding already returns a minimum of 1.
+- Scaling: Return if there are no measurements.
+  it should not be the case because the measurements come from
+  successful results, but otherwise it'd throw an exception.
+- Tests: Add bw filtered from results.
+- Scaling: round bandwidth filtered.
+  because Torflow does it.
+- Scanner: Return from measure if no helper.
+  After refactoring in #40041, it was forgotten to return the error in
+  the case a helper was not found, what can happen in test networks.
+  Closes #40065.
+- Tests: debug log for tests by default.
+  and fix test that didn't consider that there might be other logs from
+  other threads.
+  Closes #33797.
+- Scanner: Log times kept.
+  not only the times that are not kept.
+  Closes #40060
+- CI: Temporal workaround for #40072.
+- Relalist: Use the consensus timestamp.
+  to the relay consensus timestamps list, so that it can be
+  tested it was in a concrete consensus.
+- CI: Exit from integration script.
+  when any of the commands fail.
+- CI: Update Python versions.
+  Closes #40055.
+- CI: Update tor versions.
+- System physical requirements.
+  After fixing #40017, the datadir files are compressed after 29 days and
+  deleted after 57. However the total used disk space is less than 3G,
+  leaving 3G as precaution.
+  Closes #40044.
+- Scanner: Return from measure if no helper.
+  After refactoring in #40041, it was forgotten to return the error in
+  the case a helper was not found, what can happen in test networks.
+  Closes #40065.
+- Update differences Torflow/sbws.
+  Closes #40056
+- Reorganize Torflow aggregation.
+  - reorganize sections
+  - add diagrams and links
+  - add pseudocode
+  - remove math
+  - correct statements
+  So that it's more accurate and easier to understand.
+- Docs: Rename section, add diagrams.
+- Separate Torflow/sbws differences.
+  into a new file.
+- Add target to call plantuml.
+  and generate .svg from .puml files.
+  Do not add to the html target since the generated svg images are
+  not deterministic and will change every time `plantuml` is call.
+- Separate how scanner and generator work.
+  in different files and link to each other.
+- Add missing new lines.
+- CI: Make wget quiet.
+  to avoid many lines of non useful text the CI.
+- Scanner: Rm condition assigning helper.
+- Scanner: Move as_entry/as_exit into one function.
+  since they're similar code
+- Scanner: remove relay to measure as helper.
+- Scanner: log exit policy when stream fails.
+- Relaylist: Remove duplicated can exit methods.
+  After refactoring and making clear when we were using exit(s) that can
+  exit to all public IPs (and a port) or only some, refactor them
+  removing the duplicated code and adding the `strict` argument.
+- Add relay measure activity diagram.
+- Scanner: extract method on circuit error.
+  At some point all possible errors should be exceptions.
+- Scanner: extract method for not helper case.
+- Scanner: extract method to create paths.
+  because `measure_relay` method is too long, confusing and we have had
+  several bugs in this part of the code.
+- Relaylist: Add methods to obtain exits that.
+  can exit to some IPs.
+  To use them in the cases it will be more convenient.
+- Relaylist: rename exits_not_bad_allowing_port.
+  see previous commit
+- Relaylist: rename is_exit_not_bad_allowing_port.
+  see previous commit
+- Relaylist: rename can_exit_to_port.
+  to can_exit_to_port_all_ips, because it's using `strict`, which means
+  that it allows to exit to all IPs.
+  It seems more convenient to try first with exits that allow to
+  exit to some IPs and only try a second time if that fails, because
+  there are more.
+- Resultdump: Check that the error has a circuit.
+  Because if the error is not a circuit error, it does not have that
+  attribute.
+- Tests: Run integration tests with chutney.
+  and adapt the tests to pass.
+  \o/
+- Add chutney configuration.
+  and scripts to run the integration tests with chutney.
+  It does not replace yet the way integration tests are run.
+- Stem: Move torrc option that does not depend on config.
+  It seems we forgot this option when refactoring in #28738.
+- Stem: Remove torrc option that is the default.
+  to avoid conflict when comparing the options that should be set and the
+  ones are set, since the SocksPort will be differently in chutney.
+- Resultdump: Log if relay was measured as exit.
+  or entry.
+  Closes #40048
+- Relaylist: Stop measuring relays not in the consenus.
+  as this might cause many circuit errors.
+  They're already added to the generator.
+  Also adapt the number in test_init_relays.
+- Sphinx warnings when creating documentation.
+  This should give us at least a clean html, text, and man build
+  experience.
+  Closes #40036.
+- Add forgotten image from consensus health.
+  It was referenced by 6e6a8f3ba534cbd93b830fe3ffd5ce40abe8e77d. Since that
+  image was wrong, created a new screenshot from the current "past 90
+  days" at consensus-health.tpo.
+- Stem: Add possible exception cause.
+- Stem: Remove unused code.
+- Stem: Exit on failure connecting to control port.
+  because when trying to connect to an external tor (chutney), it does
+  not make sense to start own tor.
+  Also log how the connection has been made.
+- Update values in config_tor.rst + clean-up.
+  Closes #40035.
+- Update default values in man_sbws.ini.rst.
+  Closes #40034.
+- Clean up config.rst.
+  Closes #40033.
+- Scanner: Retry to measure exit as exit.
+  if it fails to be measured as entry.
+  Mayb closes: #40029.
+- Relaylist: Comment on IPv6 exit policy.
+  that could be also checked, increasing the chances that the exit can
+  exit to our Web servers.
+  But if it could not, then we need to retry to measure it as 1st hop.
+- Config: Increment circuit build timeout.
+  setting it to the default, 60secs.
+  Since many relays fail to be measured cause of circuit timeout.
+  Maybe closes #40029.
+- Bump bandwidth file version to 1.5.0.
+  after removing KeyValue recent_measurement_attempt_count in #40023.
+  Changed also torspec, issue #20.
+- V3bwfile: Tor version added in bandwidth v1.4.0.
+  since, by mistake, the bandwidth file version here was never updated
+  to v1.5.0.
+  This patch only changes the constants names, but logic remains the same.
+  Related to torspec#35.
+- Add the bwauths timeline wiki.
+  Closes #40013.
+- Add bwauthealth tool.
+- Add consensus health page.
+  about bwauths measured relays.
+- Move consensus weight to top.
+  and explain what to check.
+- V3bwfile: Take all measurements when IP changes.
+  Previously, when a relay changes IP, only the measurements with the
+  last IP were considered.
+  Relays with dynamic IP could get unmeasured that way.
+  Now, all the measurements are considered.
+- V3bwfile: Avoid statistics without data.
+  If mean or median argument is empty, they throw an exception.
+  This can happen when the scanner has stopped and the result is
+  stored as successful without any downloads.
+- No need to use Travis anymore.
+- Clarify branch to use when contributing.
+- Maint: Fix linter error after merging #29294.
+- Tests: Stop converting boolean key to int.
+  Conversion only happens when parsing a bandwidth file in the
+  integration tests.
+- Relaylist: filter out private networks.
+  when checking exit policies to know whether an exit can exit to a port.
+- Update authors.
+- Replace docs links from Github to Gitlab.
+- Update reviewers.
+- Replace Github review process to Gitlab.
+  Replace also Github terminology to Gitlab.
+- Replace Trac, ticket by Gitlab, issue.
+- Replace links from Trac to Gitlab.
+- Start using release script later.
+  Change the version from which the release script is used.
+  Also explain the prefixes used in the commits.
+  Closes #29294
+- Scripts: Clarify the scope of the script.
+  it should not take more effort than solving self-sbws issues.
+- Scripts: Reformat sentence.
+- Scripts: Stop bumping to next prerelease version.
+  since it is now managed automatically by versioneer.
+  Instead, suggest creating a "next" maintenance branch.
+  But stop using `-` and `.` characters in it, to type it faster, since
+  most of the new branches will be based on it.
+- Scripts: Stop releasing from -dev0 version.
+  since now sbws version is calculated from last release tag.
+- Scripts: Stop changing version in __init__
+  Since it is now done by `versioneer`.
+- Scripts: Change Github by Gitlab.
+  releases can live now in gitlab.tpo, instead of github.com and
+  there is no need to check them since Gitlab is FLOSS and gitlab.tpo is
+  hosted by Tor Project.
+  Also, stop assuming which is the current branch and remote and do not
+  push. Instead guide the maintainer to do it.
+- CI: Add .gitlab-ci.yml to run tests in Gitlab.
+- Relaylist: Check exit to all domains/ips.
+  When an exit policy allows to exit only to some subnet, it is not
+  enough to check that it can exit to a port, since it can, but it might
+  not be able to exit to the domain/ip of the sbws Web servers.
+  To ensure that without having to check whether it can exit to a
+  specific domain/ip, we can query the exit policy with `strict`.
+  Closes #40006. Bugfix v1.0.3.
+- V3bwfile: Count relay priority lists.
+  and measurement attempts from all the results.
+  Until they get properly updated.
+  Also change dates in tests, so that timestamps are counted correctly
+- Recomment maint-1.1 for production.
+- Recommend using a CDN,
+  add link to it and rephrase some sentences.
+- Increase RAM required.
+  ahem, because of all json it has to manage in memory.
+- Recommend pip only for development.
+  or testing and add links.
+- Update supported Python versions.
+- Comment on Debian/Ubuntu releases.
+  because sometimes the package might not be in Debian stable or testing
+  and we are not checking Ubuntu releases.
+- Tests: Remove all the `\t` in torrc files.
+  at the beginning of the line and in empty lines. They are not needed.
+- Tests: Create new authority keys.
+  because they expired.
+  They will expire again in a year.
+  Implementing #33150 and using chutney would avoid to update keys.
+  Closes #34394.
+- V3bwfile: linter error with new flake version.
+- Add differences between Torflow and sbws.
+  Closes #33871.
+- Update/clarify Torflow aggregation.
+- Docs: Remove unneeded linter exception.
+- Docs: Move torflow scaling docstring to docs.
+  so that it has its own page as it is too long as docstring and is
+  harder to write latex with the docstring syntax.
+- Unrelated linter error.
+- V3bwfile: Remove unneeded minimum 1.
+  since rounding already returns 1 as minimum.
+- V3bwfile: Use cap argument to clip scaled bw.
+  Make test pass, though the value is not correct since it needs to be
+  rounded after clipping
+- V3bwfile: cap is never None.
+- V3bwfile: Warn about None bandwidth values.
+  since they are probably due a bug.
+- Check that log prints a number.
+  and not a list of timestamps.
+- Assert that caplog messages were found.
+- Explain changes in the previous commits.
+- Tests: Check the files generated in test net.
+  Test that the results, state and bandwidth file generated by running
+  the scanner and the generator in the test network are correct.
+- Tests: Add tests loading results.
+  in ResultDump and incrementing relay's monitoring KeyValues.
+- Tests: Add results incrementing relays'
+  monitoring KeyValues.
+- V3bwfile: Stop calculating failures with 0 attempts.
+- Relaylist: Count recent relay's monitoring numbers.
+  using timestamps class.
+  Additionally:
+  - fix: relayprioritizer: Replace call relay priority
+  - fix: scanner: Replace call relay measurement attempt
+- State: Let json manage data types.
+  Since state uses json and json will raise an error when it can't
+  decode/encode some datatype.
+- State: Read file before setting key.
+  Otherwise, if other instance of state set a key, it's lost by the
+  current instance.
+  Bugfix v0.7.0.
+- Tests: Test state file consistency.
+  Test that two different instances of state don't overwrite each other.
+  This test don't past in this commit, will pass in the next bugfix.
+  Bugfix v0.7.0, which claimed 100% test coverage on state.
+- Tests: linter error cause missing nl.
+- Relaylist: Update relay status before consensus.
+  Update relay status before updating the consensus timestamps
+  Timestamps that are not old yet were getting removed because the
+  document.valid_after timestamp was still the one from the previous
+  consensus.
+  Closes #33570.
+- Tests: Test the number of consensus in Relay.
+  This test does not pass in this commit, but in the next bugfix.
+- Relaylist: Use is_old fn removing consensus.
+  since the logic is the same and the there were two bugfixes on the
+  same logic.
+- Relaylist: Use seconds removing consensuses.
+  by default days is passed to timedelta, what was making the oldest
+  date be thousands of days in the past.
+  Bugfix 1.1.0.
+- Tests: Add relaylist test.
+  Tests don't pass in this commit, they're fixed in the next commits.
+- Tests: Add mocked controller fixture.
+  to be able to unit test all the code that needs a controller.
+- Tests: Add test for remove old consensus ts.
+  Tests don't pass in this commit, it's fixed in the next commits.
+- Timestamp: measurements period is in seconds.
+  by default days is passed to timedelta, what was making the oldest
+  date be thousands of days in the past.
+- Timestamp: Old timestamps are minor than older.
+  Old timestamps are minor than the older date, not major.
+- Relaylist: Stop passing argument to self.is_old.
+- Tests: Add test timestamp.is_old.
+  The tests don't pass in this commit, it's fixed in the next ones.
+- V3bwfile: Reformat to don't get flake8 errors.
+  Part of #30196
+- V3bwfile: Move keys to correct constant.
+  Part of #30196.
+- V3bwfile: Add comment about bwlines v1.3.
+  Part of #30196.
+- V3bwfile: Add tor_version KeyValue.
+
+  - Create new KeyValues constants for the new v1.5.0 KeyValues
+  - Instantiate State in Header.from_results so that there is no need
+    to create new methods for all the header KeyValues that are read
+    from the state file
+  - Add tor_version to the kwargs to initialize the Header
+  - Write tor_version in the state file when the scanner is started
+- V3bwfile: Add constant for ordered key/values.
+  to build the list of all keys from it and ensure no key is missing.
+- V3bwfile: Reformat to don't get flake8 errors.
+  After the automatic constants renaming, fix the flake8 errors by
+  reformatting automatically with `black`, only the lines that had
+  errors.
+  Part of #30196
+- Document why ersioneer to obtain version.
+- Add at build time the git revion to version.
+  Instead of having a hardcoded version, calculate the version at build
+  time making use of `git describe --tags --dirty --always`.
+  This way, even if the program is not running from inside a git
+  repository it still can know which was the git revision from the
+  source it was installed from.
+  If the program is launched from a path that is a git repository, it
+  does not gives the git revision of that other repository.
+  If's also able to get the version when installed from a tarball.
+  It does not add the git revision when it's being install from a git
+  tag.
+  `versioneer` external program is only needed the first time, because
+  it copies itself into the repository. So it does not add an external
+  dependency.
+  There're no changes needed to the `--version` cli argument nor to the
+  code that generates the bandwidth file, since they both use the
+  variable `__version__`.
+  The version previous to this commit was `1.1.1-dev0`, after
+  this commit, it becomes `1.1.0+xx.gyyyyyyyy`, ie. xx commits after
+  `1.1.0` plus the git short hash (yyyyyyyy).
+- Tests: Test maximum retry delta in destination.
+- Destination: Replace constant name.
+  to make it consistent with others and shorter.
+  Part of #33033.
+- Destination: Set maximum to retry a destination.
+  otherwise the time to retry a destination could increase too much,
+  as it's being multiplied by 2, and a destination would not recover.
+  Patch submitted by tom.
+- Relaylist: linter error after after merge.
+  Fix linter error after merging #30733 and #30727.
+- CI: Cache pip, run tox stats after success.
+  and do not require sudo.
+- CI: Test all supported python versions.
+  As in chutney and stem:
+  - Test all supported python versions
+  - Test all supported tor versions
+  Differences between chutney, stem and sbws:
+  - in sbws we run directly, not an script that calls tox
+  - we're not using chutney for integration tests (yet) and therefore we're not testing it with different networks
+  - we don't have shellcheck tests
+  - we don't support osx nor windows
+- Relaylist: Update the relays' descriptors.
+  when fetching new consensuses.
+  Part of #30733.
+- Globals: Fetch descriptors early.
+  and useless descriptors, so that sbws detect early changes in the relay
+  descriptors and continue downloading them even when Tor is idle.
+
+Other
+~~~~~
+- Wip: rm me, temporally change release url.
+  to personal fork, to test the release process
+- Fixup! minor: Change info logs to debug or warning.
+- Major: Change default log level to info.
+  also change formatting to show thread.
+- Minor: Change log warning to info or debug.
+  when it contains sensitive information.
+- Minor: Change info logs to debug or warning.
+  when they contain sensitive information, eg. Web server or are too
+  verbose for the debug level.
+  Also add log to indicate when the main loop is actually started.
+- Revert "fix: stem: Remove torrc option that is the default"
+  This reverts commit 15da07d6a447d8310354124f6020b4cf74b75488.
+  Because it's not the default. No additional changes are needed in the
+  tests.
+  Closes #40064.
+- Minor: scanner: Change logic creating the path.
+  When the relay is not an exit, instead of choosing exits that can
+  exit to all IPs, try with exits that can exit to some IPs, since the
+  relay will be measured again with a different exit in other loop.
+  When the relay is an exit, instead of ensuring it can exit all IPs, try
+  using it as exit if it can exit to some IPs.
+  If it fails connecting to the Web server, then try a 2nd time using it
+  as entry to avoid that it will fail in all loops if there is only one
+  Web server, cause it will be used again as an exit.
+  Also, the helper exits don't need to be able to exit all IPs. When a
+  helper exit fails to exit (maybe cause it can not exit to the Web
+  sever IP), it's not a problem cause in a next loop other exit will be
+  chosen.
+  This change of logic also solves the bug where non exits were being
+  used as exits, because we were trying to measure again a relay that
+  was used as entry, because it could not exit all IPs, which includes
+  also the non exits.
+- Minor: scanner: move checking helper to methods.
+  `helper` variable is only used to return error, therefore move it to
+  the methods that create the path and return the error there.
+  `our_nick` is not useful for the log, since it is always the same, but
+  not removing it here.
+- Vote on the relays with few or close measurements.
+  to vote on approximately the same numbers of relays as Torflow.
+  Torflow does not exclude relays with few or close measurements, though
+  it is possible that because of the way it measures, there are no few
+  or close measurements.
+  Closes #34393
+- Doc: fix: Update sbws availabity in OS and links.
+- Bug 33009: Require minimum bandwidth for second hop.
+- Use freeze_time() in other parts of our tests, too.
+  When using `_relays_with_flags()` and similar methods it's possible
+  that tests start to hang without time freezing. See bug 33748 for more
+  details. We work around this by providing the necessary `freeze_time()`
+  calls meanwhile.
+- Bug 33600: `max_pending_results` is not directly used in `main_loop`
+- Fixup! fix: CI: Test all supported python versions.
+- Relaylist: stop using the current time when a consensus is downloaded twice.
+  Instead:
+  * use the consensus valid-after time, or
+  * use the supplied timestamp, or
+  * warn and use the current time.
+  This should fix the occasional CI failure, when the current time is 1 second
+  later than the test consensus time. (Or it should warn, and we can fix the
+  test code.)
+  Fixes bug 30909; bugfix on 1.1.0.
+- V3bwfile: skip relay results when required bandwidths are missing.
+  Fixes bug 30747; bugfix on 1.1.0.
+- Bump to version 1.1.1-dev0.
+
 v1.1.0 (2019-03-27)
